Out of everything in your backpack, personally, a pencil must be one of the most important supplies. That’s why a pencil sharpener must be in at least the top 5 most important. Here is how pencil sharpener is made.
How Does a Pencil Sharpener get into my Backpack?
1) A rod of, most likely magnesium, is cut into small, metal cubes.
5) Then the block is trimmed down so nothing cuts the user.
3) All of the blocks are put onto a conveyor belt, where they will get a hole drilled into the side of them. Another hole is drilled into the top for where the metal screw that holds everything together is supposed to go.
- 2) These blocks are put into a bin all together and sent into a machine. This machine shapes the soon to be sharpeners so that there is grip for the user.
4) Another machine cuts out the area that the blade will go.
6) The blocks are washed in, most likely, nitric acid
How Does a Mechanical Pencil get into my Backpack?
1) At a factory, the mechanical pencil barrel is made with a machine. Here, the tip is also made. The tips of the pencils are made with screw indentations for an extra grip on the pencil. These parts are taken to an assembly plant.
This mixture is heated, then rolled out. Afterward, it is cut.
Nowadays, there are no more regular pencils. You know what replaced them? Mechanical pencils. Now you don’t have to be that one kid who decides to sharpen their pencil as a teacher is talking. Let’s find out how these innovative pencils are made:
Now let’s find out how the lead/graphite is made:
First, pencil lead is made up of a mixture of graphite and clay.
Lastly, the lead is sent to the assembly plant
How Does a Binder Get into my Backpack?
A binder is one of the necessities in school as you get older. The way that they are made ensures a last throughout the whole year. This is how a binder is made.
5) Three binder rings are put on. The rings are a metal surface with alike rings attached. This is stuck onto the spine using different types of pins.
1) Plain 2 feet long pieces of cardboard are cut about 12x11 inches.
3) So the sheets will stick even more together, a sewing machine-like mechanism joins these layers by ‘sewing’ the edges.
2) This board is covered in a fine paste that will adhere a plastic layer for the top and all around. This plastic is put on the board.
4) A rolling pin-like machine pushes down on these joined layers to take out all of the air bubbles. This makes the board nice and smooth, it also joins these layer even more ( as if it’s not secure enough already! ).
How Does a Water Bottle Get into My Backpack?
If you look around a classroom, you can see that around half of a class has something that varies in color, shape, and size. What is it? It’s a water bottle! Bottled water has been around since 1621, and now there are water bottles that keep the drink cold/hot, fruit infused, and so much more! But, how are the most common water bottles made?
2) These pieces of plastic are put into another frame with a little, circular shaped mold. This tube-shaped object is then moved into a third frame with the shape of an actual water bottle.
1) These bottles start as pieces of plastic that no one loved, and they are warmed and put into shaped frames.
How Does a Highlighter Get into My Backpack?
5) The clear tubes are put onto a conveyor belt.
Imagine the world without highlighters. That would be a very very sad and dark place of underlining? Let’s find out how these majestic neon wonders are made:
3) Water cools the plastic.
1) Plastic pellets are put into a machine that will melt them. A couple of the pellets are different colors, like yellow and pink. These are here so the plastic has some color.
7) To make the ink, a few drops of dye are put into a beaker of water.
6) A machine inserts the ink cartridges into the clear tubes. Immediately after, the backs to the highlighter are put into the end of the highlighter tube.
2) A screw made out of steel pushes the melted plastic into molds that look like a highlighter. The force of this machine is equivalent to about the weight of 244,186 gallons of milk.
4) All of the plastic tubes are placed into a bin altogether.
Remember in kindergarten, when all you did was use markers. Sure, if you pressed too hard the paper would rip, but it was ART. But have you ever asked, in your several years of life, how is a marker made? If you have, you have come to the right place.
How Does a Marker Get into My Backpack?
2) To finish off the marker body, a machine assembles all of the parts together.
1) In a very similar way to how the highlighter plastic was made, a batch of plastic is made.
This plastic is injection molded into a marker body.
You may wonder, ‘What’s injection molding?’, injection molding is when a material is heated into a liquid form, and being shoved or injected into a template of your desired shape. Then letting it dry and solidify.
How Does a Composition Notebook get into my Backpack?
The composition notebook has been used for ages. The cover type of design were first presented in China, in the 10th century! These books are used by many artists. But, how are they made? Let’s see!
1) Chopped wood is processed into pulp using a machine.
3) This bleached paper-like pulp is spread out onto frames and set out to dry.
1) Composition notebook covers used to be made using a technique called pseudo marbling. But now, the cover's design is printed onto pieces of cardboard.
Paper is surprisingly made from trees! But, we don’t just chop slivers of a tree and call it a day. This is how the paper is made:
2) This pulp is bleached, and the cellulose fibers are removed.
